RESILIENT WHEEL.

I Specification of Letters Patent. Patented Sept. 28, 1915;

Application filed June 25, 1913. Serial No. 775,761.

Be it known that I, An'r'rtmr JUT1LA,=EL subject of the Czar of Russiaand Grand Duke of Finland, residing at Orr, in the county of St. Louisand State of Minnesota, have invented certain new and usefulImprovements in ResilientVVheels, ofwhich the following is aspecification.

This invention relates to an improvement.

in resilient wheels. 1 H ,1

The primary object of the present invention is to improve theconstruction shown in my patent granted the 8th day of August, 1911, No.1,000,013.;

Broadly the above mentioned patent .covers a hub, froniwhich projects aplurality of spokes, and a rim provided with brackets disposed to extendbetweenthe spokes of the hub, there being springs connecting theterminals of the spokeswith the brackets to cushion the hub as the loadis applied.

The present invention is designed to im-'.

prove particularly the construction and arrangement of the resilientconnection be-' tween the spokes and the rim, whereby: a

v'ided.

A further object of the invention is to provide a constructionwhich,when used on the drive wheels of motor vehicles, w ll not become wheelis mounted, i

A still further ob ect of the invention '18 to so construct the springmembers, which constitute the cushioning means,tha'twhile they willeffectually cushion thespokesxin their movement with respect to the hub,they will be sufficiently strong to withstand the pressure exerted ontheme 7 Another object of the invention is to provide an attaching meansfor the springs whereby they may be interchanged'without disassemblingthe wheel. H

For a fullunderstanding of the invention, reference is to be had to thefollowing'description and accompanying drawings, in

which:.' I

Figure 1 is a side elevation; Fig. 2 a section taken onqthe line 2- -2,certain of the parts being omittedto more clearly bring out theconstruction and arrangement of the ring which embraces the hub andwhich has a flexible connection withthe rim; Fig. 3 a detail viewshowingthe arrangement of y the springs; Fig. 4; a transverse sectiondisarranged or distorted when power is applied to the axle onwhich thethrough the rim showing the manner in which the springs aresupportedthereon; and Fig. 5 a detail view of the spring supporting member whichis secured to the spokes.

Corresponding and like parts are referred to in the followingdescription and indie cated' in all the viewsof the accompanyingdrawings by the same reference characters.

In the drawings, 10 designates; a ,hub;

which is formed with the axle receiving pertion llfand the spacedflanges 12 and 13.

The spokes M are pivotally mounted between the fianges 12and 13, bolts15 passing through the flange 13 and the terminals of. the hub, theflange 13 constituting a plate.

The bolts 15 pass through apertures 18 in the iiange13, the heads ofsaid bolts con tacting with the flanges The terminals of the bolts whichproject throughthe flange 12 receive cotter pins. It will be noted bythis construction that by removing the cotter pins, the. spokes the hub.

The periphery of the flange 15 is scalloped;

and provided with a series of apertures 19.

' A ring 20 is supported; in a manner hereinafter described adjacentthefiange 13, said ring being. formed with a plurality of radial, Theseextensions are -alter-.

with an extension 27 formed with a thread.

lt may be removed from.

ed bore which receives the terminal of the a l spoke. The housingcomprises a base plate,

28 from which extends at right angles aside plate 29, there being a topplate 30 disposed parallel with the plate 28. The side wall 31 of thehousing is removable, being formed,

with an aperture receiving an extension 32 carried by the base plate, acotter pin'being inserted through said extension tosupport the side wall31 against'removal. The top ofthe housing is formed with a flange/3,3beneath which the edge 34 of the =plateZ-BO extends, the plate in thismanner being cf: fe'ctually held against displacement.

. A web 35 connects'the upperand lower plates being provided withflanges 36. A

plurality of coiled springsare supported on each side of the housing,said springs being of greater diameter at their terminals than at theircenters. nate in plates37 which are inserted in the guide-ways 38 of thehousing formed by the flanges 36,t he plate 37 preventing thedisplacement ofsaid springs. In the drawings, each housing supports foursprings, two on each side. It will be noted, however, that when thewheel is used for heavy trucks, the length of the housings may beincreased and any number of springs employed.

The rim 39 which may be of any suitable construction, and on which maybe supported a metallic or cushion tire, is provided at intervalsthroughout its circumference with spring supporting devices 40. Thesedevices consist of brackets, there being a bracket disposed between eachpair of spokes." The brackets are substantially V- shaped in endelevation and comprise converging plates 41 and 42 provided with flanges43 which are secured to the rim. 'Gruideways 44 are formed on each ofthe plates. the guideways'extending entirely across the plates and beingclosed at one end. A plate 45 is secured to the bracket at the open endsof the guideways, closing the guideways, one edge of the plate beingsupported by lugs 46 formed integral with the bracket.

A lug 47 extends from thebracket and pro jects through the plateadjacent its edge remote from the lugs 46, a cotter pin extendingthrough the lug 47 and supporting i the hub.

the plate 45 against displacement. The terminals 48 of the springs aresupported by the brackets 40, the plates 37, which are either formedintegral with or secured to the springs, being inserted within theguideways 44. Thus the springs are interposed between the spokes and therim, the spokes in their movement when the load is applied beingcushioned and relieving the jar on In wheels of this character wheresprings are interposed between the rim andhub, the

wheels when applied to the driving axle of a vehicle become distortedwhen power is applied to the axle. In order to prevent the displacementof the springs in the present construction, the outer rim is connectedto the ring 20 by a steel wire 49[ This wire 49 is passed beneath thehooks 22 of the ring I 20 and drawn outwardly toward the rim, the

loops thus formed passing through the enlarged terminals 50 of screws51. The screws '51 are mounted in the lugs 52 carried by the brackets40, and the tension of the wire may be regulated by adjusting the screws51. It will thus be noted that the ringQ-O will be supported adjacentthe hub The springs termiand restricted in its movement by the flange13, the projections 23 which extend through the openings Not the flangeguiding the ring in its movement. The cushion 25 when the ring is movedwith respect to the hub contacts with the hub and takes up jar that,might occur. 7

It will be noted by this construction that when the wheel is arranged onthe driveshaft of a motor vehicle andpower is applied, the outer-rimwill not rotate with respect to the hub to an extent which would distortor displace the springs, the means by which this is accomplished,however, being such as not to interfere with the cushioning action ofthe springs.

The many advantages of aconstruction of this character will be clearlyapparent as it will be noted that while the hub is efl'ec- 'tuallycushioned when the load is applied or distorted when power is applied tothe shaft on which the wheel is mounted. It will also be seen that thestructure may be. easily and economically manufactured and that thesprings may be readily replaced should they become worn or damaged.Attention is-called to the fact that the entire structure is such thatthe various partsmay be readily assembled.
